SAFETY-HEEL.

Application filed April 10, 1914.

T all whom it may concern:

Be it known that I, ALBERT C. RIGH'roR, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Safety-Heels, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to antislipping devices for boots and shoes, particularly those capable of being thrown into and out of operative position to engage the surface walked upon at the will of the user, and has for its objects to provide a simple, inexpensive, practical, eflicient and convenient device of this character, one which is well adapted for use in connection with rubber and other resilient heels, and one which may be readily applied to an existing boot or shoe without other modification of the heel thereof than the removal of the usual num ber of lifts incidental to the application of a rubber heel or lift of ordinary form.

The foregoing and other objects of the invention, together with means whereby the same may be carried into effect, will best be understood from the following description of one form or embodiment thereof illustrated in the accompanying drawings. It will be understood, however, that the particular construction described and shown has been chosen for illustrative purposes merely, and that the invention, as defined by the claims hereunto appended, may be otherwise embodied and practised without departing from the spirit and scope thereof.

In said drawings: Figure 1 is a longitudinal vertical section of a safety heel or auxiliary lift and associated devices constructed in accordance with the invention, a portion of the regular heel lifts and other parts of the shoe being shown in side eleva tion. Fig. 2 is a bottom plan view partly broken away. Fig. 3 is a section on the line 33, Fig. 1, showing the antislipping device in retracted or inoperative position. Fig. 4 is a similar view showing the anti slipping device in projected or operative position. Fig. 5 is a top plan View of the auxiliary lift. Fig. 6 is a perspective View of the plate associated with the auxiliary lift and carrying the operating means for the antislipping device.

The complete device constituting the present invention comprises an auxiliary heel or Specification of Letters Patent.

outer lift 12, preferably of rubber or other suitable resilient material, and certain associated parts, said complete device being adapted for application to the regular heel 13 of an ordinary boot or shoe in substitutlon for one or more of theouter lifts of said regular heel in a manner similar to the application of the well-known rubber heels or lifts now in extensive use. Associated with the auxiliary lift and interposed between the same and the heel 13 is a plate 1 1, preferably of metal. The plate 14: is provided on its under side with transversely arranged guide flanges 30 for a purpose presently to be explained. The flanges 30 are preferably formed integral with the plate 14, being struck up from the body of said plate, thereby leaving openings 17. The auxiliary heel or lift 12, together with the plate 14, is secured to the heel 13, after the removal of the necessary number of lifts, by means of nails 16 which pass through the openings 17 in the plate 14 and nails 18 which pass through other suitably disposed openings 19 in the plate 14:, said nails 16 and 18 entering the heel 13. The auxiliary lift 12, when composed of rubber or the like, preferably has embedded therein at suitable point washers 20 through which the nails 18 pass, said washers engaging the heads of said nails and preventing said heads from pulling through the rubber lift 12.

The creeper, calk, or antislipping device 21 preferably comprises a block or plate having a roughened outer surface or edge and is arranged for vertical movement in a slot 22 extending through the auxiliary lift 12 and arranged transversely thereof. When said auxiliary lift is composed of rubber or the like there is preferably embedded therein a plate 23 having a central opening to receive the calk or antislipping device 21, thereby guiding said antislipping device for vertical movement and preventing lateral displacement thereof. The plate 23 is preferably formed with suitably disposed openings through which the nails 16 pass, thereby not only securing said plate directly to the heel 13 but also preventing the heads of said nails from pulling through the rubber lift 12. The antislipping device 21 is moved upwardly into its inoperative position within the heel by means of a leaf spring 24 secured at one end to the under surface of the plate 14 adjacent the rear 1 6, thereof and engaging at its free forward end a slot 25 in the antislipping device 21. Said spring 24 is received in a recess 26 formed in the upper surface of the auxiliary lift 12 and extending rearwardly from the slot 22. The means for projecting the antislipping device 21 downwardly into its op-' erative' position against the tension of the and cooperating with an upper cam surface 29 on the anti-slipping device 21. The cam slide or plate 27 is guided for lateral movement in the slot 22 between the flanges 30 on the plate 14 which extend into the slot 22, said slot being formed with a flared upper end to receive said flanges. The cam plate 27 is operated to project or release the antislipping device 21 by means of a lever 31 pivoted adjacent its center, as at 32, to the plate 14 and at its-rear end on a pin or stud 33 projecting upwardly from the cam plate 27 within a recess 34 in the upper 'face of said cam plate into which the end of said lever extends. The lever 31 is received in a. recess 35 in the upper face of the auxiliary lift 12, said recess extending forwardly from the slot 22 to the breast of the heel beyond which the forward or operating end of the lever 31 projects.

The normal or inoperative position of the parts is as shown in Figs. 2, 3 and 6 and in full lines in Fig. l, in which position the antislipping device 21, under the influence of the spring 24, is lifted into a position entirely within the lift 12 and above the lower surface thereof, so as to be out of engagement with the surface walked upon. At this time the position of the cam plate 27 is such as to permit such lifting of the antislipping device 21 by its spring 26, i. 6., the high portions of the cam surface 28 are opposite low portions of the cam surface 29, and vice versa. In order to project the antislipping device into operative position, as shown-in Fig. 4 and in dotted lines in Fig. 1, for use on slippery surfaces,-the forward end of the lever 31, which is extended to a convenient point in front of the breast of the heel and beneath the instep, is moved transversely of the heel, thereby swinging said lever on its pivot 32, and moving the cam plate'27 from the position shown in Fig. 3

v into that shown in Fig. 4. During this movement of the cam plate 27 engagement of the cam surface 28 with the cam surface 29 causes the antislipping device 21 tobe projected downwardly into operative position against the tension of the spring 24. The cam surfaces 28 and 29 are so formed that, when the cam plate 27 is moved into the extreme position shown in Fig. 4, interengagement of high portions of said surfaces will cause said antislipping device to be positively. locked in its operative position, up-

the plate 14 and heel 13.

Having thus described my invention, I
